So I'm new to the CamillaDSP and other signal processing part of moode, does it effect all playback? will the polarity inversion effect Airplay and Spotify also? I just want to make sure the polarity is correct, but honestly I'm not really sure if my system has anything else inverting.

Is there a good way to test this at the speakers?

Polarity inversion will affect all playback. Polarity inversion can also be done in MPD.

Most equipment does not invert polarity. If it does, it should be stated in the manual.

The only way to know is to display the input and output on an oscilloscope. Or the input could be mixed with the output in a mixer. If the output of a stage is inverting, the sum of the input and output will be zero (complete cancellation if the amplitudes are the same).

When the polarity is correct, the sound quality is better in comparison to inverted.
